To all whom t may concern.: n

Be it known that I, FRANK I'I. 'EYMAIQ a citizenof the United States, residingl in Oak Park, in the county of Cook and State a of Illinois, have invented certainnew and useful Improvements in Seal Presses, or" which the following is a specication.

This invention relates to presses having a frame provided with jaws adapted to ad- 1H mit material therebetween to be operated upon, and having an operating lever for operating a movable seal, die, punch kor other similar element for operating upon such material.

The principal object of the invention is to provide a simple, economical and eiiicient press for operating Va seal, die, punch, or similar element to impress or periorate a sheet Or other structure to be operated upon, and to provide simple and eflicient means for distributing or equaliiing and.V

regulating or controlling the degree of pressure to be applied or obtained in the operation of the device. n

Other and further objects of the invention will appear from the following description and claims, and from an inspection of the accompanying drawings which are made a part hereof. Y

The invention consists in the features, combinations and details of construction and arrangement of parts herein described and claimed. n y,

In the accompanying drawings,

Fig; 6 is an enlarged perspective view `in detail of the adjustablefpressure distributing and controlling means shown in In constructing a press adapted to operate a seal,'die, punch, or similar impression or perforatingmember, in accordance with my invention, I provide a frame l having trame arms or jaws which, in the form or table,k or other support, or maybe of any form and dimensions suitable `for enabling the seal pressto be graspedv and supported ,in one handpandv operated thereby, while the sheet or materialtobe operated upon kor impressed with the imprint oi the seal or die is held in position between the fopposed die members or impression members by the The frame l, as, well as the operating lever 5, may be ormedoi pressed sheet steel, or other suitablesheet metal, or may be cast, if desired. But I prefer to make them of hollow light construction, but suliciently strong and rigid to withstand the stresses and strains to which they are subjected in use; and/,the device' should be compact and portable. It is therefore made as light as possible consistent with the c strength required and theuses to which the mechanism is to be applied.

The upper4 frame arm or jaw 3 is, by preference, so constructed as to comprise side portions 6, 6 which are spaced apart and in parallel relationA so as to provide a space 7 therebetween in which is mounted the operating lever A5 which has integral depending side liange portions y8, 8 located between and in engagement with the op- `of the. frame may be of any suitable width .Y 'and dimensions suitableforsupporting the 'seal press in upright position on a frame or posite inner side surfaces of the side frame members 6, 6, of the upper'rigid frame arm or jaw 3, to which the operating lever is pivotally attached by means of a pivot 9 which is mounted in the upper rigid frame arm or jaw 3, in suitableperforations provided for receiving the opposite ends of the pivot. The pivot 9 thus extends transversely acrossr the space 7YV and through perforations in the depending side flange portions 8, 8, of the operating lever 5, at or near the forward end of the lever and the corresponding extermity of the upper jaw or fra-me arm 3, which thus pivotally supports the lever in position to be raised or extended, and collapsed or lowered, and locked in lowered or closed position and released and operated with facility, as desired. f

The lower frame arm or jaw 2 and the upper frame arm or jaw 3 are spaced apartso as to provide a space 10 therebetween adapted to admit the dies, seal members or other Vparts to be operatedk and supported in operative position between said upper and lower frame arms or jaws.

A lower stationary die or seal member 11, which may be in the form of what is commonly known as a splash seal, or may be a cast seal member, if desired, is mounted upon the lower rigid frame arm or jaw 2 which has a suiiciently wide, and in this instance, circular seal supporting portion or bed 12 on the upper surfaceof which the bottom die or seal member 11 is cast or otherwise lixed.

An upper movable die member or seal 13 is movably supported directly over the lower side or seal member 11 by means of vay resilient supporting member which, in this instance, is in the form of a spring 14 having a lower spring arm 15 and an upper spring arm 1G Yformed in one integral piece and mounted on the inside of and inclosed by the hollow casing or frame 1, said spring arms being spaced apart so as toprovide a space therebetween adapted to admit a sheet of paper or other material to be operated upon, and to permit the desired movement of the uppenmovable die 13. The lower' spring arm 15 is rigidly secured at its forward extremity to the upper face of the lower frame arm or jaw 2 by means of a screw 17 anchored in the lower frame portion or base, and, by preference, extending through the lower jaw 2 and in secure rigid engagement with the forward end of the spring arm 15 ydirectly back ofthe lower die 11 and its circular supportf12. Y

A sufficiently wide, and by preference, flat and circular die-supporting casing 18 is movably supported upon and, by preference, formed in one integral piece with the upper spring arm 16 of the resilient die-support 14, and provided with a depending marginal peripheral flange 19 which is Vsufnciently and are Aadapted to be clamped securely inr detachable supporting engagement with the upper movable die or seal member 13 by means of a clamping screw 22 mounted in the adjacent perforated peripheral projecting end portions 23 'of the exible flange parts 21. f

A crank pin or eccentric die-operating member 24 is provided on the operating 1ever 5 and located directly over the central portion of the upper movable die 13 and its supporting casing 18, and forms a pressureapplying member intermediate the axial pivot 9 and the movable die member 13 and support 18. And interposed between the eccentric pin 24 and die 13 is a pressure-distributing and equalizing device comprising a frame or carriage 25 having side frame portions 26 which are perforated and provided with transverse pins or axles 27, on which are mounted rotative anti-friction rollers 28 each of which is in rolling Contact with the flat upper surface of the upper die or die supporting casing 18.

These anti-friction rollers are mounted on opposite sides of the transverse center of the die-support 18 and of the upper movable die 13 supported by the resilient member 14.

The frame or carriage 25 is provided with a threaded pressure controlling or regulating adjusting screw 29, which is mounted in vertical position in threaded engagement with a central vertical screw-threaded opening 30 in said carriage or pressure distributing frame member 25. The pressure controlling or regulating adjusting screw 29 is provided with a head 31 having oneror more top transverse longitudinal notches or recesses 32 in and across its upper face and adapted to admit and pivotally engage the transverse excentric pin 24 mounted on or forming a part of the operating lever 5, already described. y

It will thus be readily understood that by turning the pressure controlling or regulating and adjusting screw in one direction the degree of pressure obtained or applied to the paper and movable die member 13 and pressure distributing carriage or shoe 25, by pressing the operating lever 5 downward to a desired predetermined positionfor example, to the position shown in Fig. 3 of the drawings-will be correspondingly increased. It follows as a matter ot course that by turning the adjusting screw 29 in an opposite direction one or more turns or partial rotations, the degree of pressure obtained or applied by the operation of the lever 'tosuch desired j predetermined lowered operative positionwill of Vpressure to be applied or obtained by the operation of the-device. The operating le-` befcorrespondinglv reduced. 'A very simple and eflicient meansis'thus provided for controlling, regulatingor adjusting thedegree ver 5 may thus be adjusted with respect to A`the movable die member 13 and pressure distributing and regulating carriage or shoe age. The operation of the device and the accurate adjustment of the upper and lower die members Vandkoperating lever withrespect to each other and the regulation of the pressure to be obtained are thus accom-` manner.

In operation,

center of which is the center ofthe transthe dies, and'. 'in case any given marginal verse pivot pin or axle 9, the pressure-distributing deviceor carriage 25 and rollers 28 will move downward with the die 13 until said die comes in contact with the stationyarylower die 11, or with the upper face `of,

a sheet of paper or other material between portionfof the movable die becomes engaged and is stopped from further movement in the direction of the lower die inadvance Yof any other portion, or before the upper and lower dies are properly engaged in uniform parallel relation, the fanti-friction rol-ler 28 which happens tov be the one located over the higher portion of the mov-V able die 13, or between the pin 24 and a portion ofthe upper movable die which is still A' to tending to press all parts of the upper die' out of contact with ormore widely separated from the lower :die than the portions first engaged and stopped from further movement toward they lower die,r`wil1 receive and transmit pressure from the pin 24 to 'the higher portion -of the upper die'and of .the

downward toward andv in parallel relation to and in uniform operative engagement with the adjacent face of the lower die or of a sheet located between theupper and lower die members. Andan evenand uni- .V forni pressure and impression is thus obtained between the adjacent opposed sur-` faces of theupper and lower die members as the lin 24is'moved d'own-V ward and forward in the arc of a circle the throughout the-entire areal or engaged vsur- -f face thereof, or of thesheet located between such parallel uniformly spaced or parallel opposed 'surfacefportions ofthe dies which are, of course, inaleand female, the outline oneione having `been impressed yupon the yadjacent opposed surface-ofthe other. s. It

is obvious that the form of ythefupper or original. die may be impresseduponv the 'lowerffdie member while the latter-is in a plastic condition, ifvdesired, Awhile Vthe mov- `able die-is mounted inthev position in which it ist@ be ,used'nwhenthe press in fin operation for they usesv forv whichl itis intended. Means for limiting themovement ofthe operating lever and of the upper ormov- `able die ortool, and for permitting the operation of the rlever to raised, openor ex-l Y .j i n tended position, and for vlocking the same plished with facility and in an effective,

in lowered closed position, is follows:V v -A 'Each of thesaid walls`33 of the operating lever 5 Vis provided with a ltransverse aperture or angular s1ot'34c, and each of said wall portions 6 of the upper arm or jaw' provided as 3 is provided with an inclinedy transverse opening or slot 35 adapted to register with a corresponding opening or slot 34 inthe operating lever 5. Y j f i Y' A locking pin kor bolt k36 is slidably mounted in, Y and in `rposition to extend through the openingsorslots 34: and35,v

and comprises in its construction ajheaded 'inner screw-threaded bolt memberor screw 37, and anv outer headed sleeve member 38 having a screw-threaded longitudinal. axial bore 39 in threaded engagement with which the threadedscrewf37-islmounted- The headof the sleeve member 318 and the head of the screw member-37 arethus `located on opposite sides of and 'in sliding engagement with the opposite outer faces of` the side walls 6 of the upper jaw or frame arm 3. The sleeve member 38 is of such. length thatl its innerend margin 40 is iny abutting engagement with ythe inner facefof the ,headA of the screw membery 37, so that the screw member v37 and thesleeve member 38 may be secured tightly together vand held firmly in rigid engagement with each other, while permitting the locking bolt or pin 36, comprising said inner and outer members 37 and 38, to be freely moved in l the slots l34 and 35 fromrupper locking position, as shown in FigQS, to lowerrelea'sing position, as shown in Fig. 2, and vice versa. The upper extremities. of the transverse slots or angular inclined yopenings 34; and 35 areadapted to register with eachother when the operating lever-5 is inlowered po# sition, with the locking `bolt ork pin36 comprising the Linner screw-threaded inember'` 137 and outerl sleeve-member.; 38-in raised locking position and ini engagement with the upper extremities ofthe lower inclined side walls 4l of the angular slots l34 in the operating'lever. And the lower eX- tremities of the transverse openings vor inclined slots 34 and 35 are adapted to register -with each other when; the operating lever 5 is in raised'or open position and the locking` .pin orbolt 36 is in lowered lever-releasingV position, as shown in FigzQ. y

kThe slots 34 and 35v are of suchtorm and dimensions, and the inclinedwalls 410i the Y -slots 34 and inclined/walls 42 of the slots 35 .slots 34 and 35 in such a manner as to pery. n. V
